This week’s problem is a twomover on the theme of half-pins and pin-mates, by
probably England’s greatest-ever composer.
The key 1.Qe7 gives a flight square and sets up a half-pin, where if either rook or
knight moves off the e-file the other is pinned. The pin-mate 2.Rxe6# is threatened,
and if Black takes the flight White replies with a cross-check - 1...Kd5+ 2.Rc2#. The
thematic variations are 1...Rd5 2.Bxg5#; 1...Sc7 2.Rxc7; 1...Sec5 2.Rxc5; 1...Sxf4 2.Rc3;
and 1...Sxg7 2.Rf6#. There is also a by-play variation 1...Sd any 2.Sf6. Godfrey Heathcote described
the problem as "The finest half-pin two-mover I know".
